  1. Differences between NW, OW, and OB were assessed using one-way ANOVA with post hoc Bonferroni correction and Kruskal–Wallis test followed by independent samples Mann–Whitney U test corrected for multiple comparisons. Difference between NW and OW/OB was assessed with independent samples t-test. P-values 0.05 were considered significant
  2. NW normal weight (BMI 18.5–24.9 kg/m2), OW overweight (BMI 25–29.9 kg/m2), OB obese (BMI 30–39.9 kg/m2), OW/OB overweight and obese (BMI 25–39.9 kg/m2), BMI body mass index, CRP C-reactive protein, IL6 interleukin-6, AGP alpha 1 glycoprotein, IQR interquartile range
  3. Values are: amedian (IQR), bmean (±s.d.) and cgeometric mean (95% confidence interval)
  4. dSignificantly different from obese
  5. eSignificantly different from OW/OB
  6. fSignificantly different from overweight
